Jerry.....In PA you absolutely CAN have lighted pin sights. What you cannot have is a sight that casts a beam directly onto the target.
Although your "Blue" light would probably scare the bejeepers out of any self respecting deer there are quite a few other more low key type lights that do a good job.
The trick to the lighted pin sight is to have it just bright enough to help in those last legal shooting minutes, but not so bright that it "halos" and blots out the target behind.
nmaine.....Shooting with conventional fiber optic pin sights (with the exception of the freak of nature Impact ARchery Cosmic<img src=icon_smile_shock.gif border=0 align=middle>)
pretty much stinks indoors......a light would be a big help for sure and that blue number Jerry mentioned is good (I've seen one in action) but I don't know if your league rules will alow it?
Also if you are shooting indoors at a fixed distance why the need for "PINS" (plural?) Why not remove the rest and concentrate on that single pin?
